Introduction What is it: What is it: A low cost instrument designed to over come the requirement of multiple snow observations over an area. What purpose does it serve: What purpose does it serve: Snow depth is spatially heterogeneous and proper assessment requires a high spatial sampling rate over a broad area to account for the variability, requiring resources and time from observers. Typical automated snow depth measurements can be cost prohibitive. Cost of instruments often forces observers to limit the number of instruments taking samples. IDASOS hopes to overcome this limitation in automation.
